I attached my FSR to a Sriracha bottle as shown in the attached photo. Since I use this spicy sauce on almost every meal and you can squeeze the bottle, I thought it would be a fun everyday object to attch the FSR to.
I then programmed a ridiculous animation to that I wanted to play when you squeezed the bottle. I programmed the animation based on the "Sequential" example under the "Animation" category.
I took a quick video of what the screen looks like here:http://vimeo.com/20276309. However, after many attempts, I could not link the FSR to the animation for the life of me. I tried many different things, I wont bother posting the mangled code as it is long and does nothing... but I will post code for the animation at the bottom.
Instead I modified the code that we were given in lab, posted below. I know it's nothing exciting, but the deadline to post the HW is near and I have a quiz in the morning to study for. Sorry, I will try to get the animation code working with the FSR later.
-- Simple (but working) Code-- Flashes Sriracha colored balls incrementally on the screen...
